Hey Jarena,
Welcome to the Forum!
What you described with the EAs happens quite often. The question is the EAs to perform profitably in the long term. There will be times when the profits will be wiped, and there will be times when the position goes on a loss but finally it closes on a profit.
That is why we have the backtest with the EAs so we can see an average performance. Did you perform backtest with your broker?
